Does Sleep Issues Cause Bipolar Disorder?
Scientists have not found a causal relationship between sleep issues and bipolar disorder. However, there may be a link between both conditions. They are associated with changes in the microstructures of the brain’s white matter. Some health experts think that the creation of bright artificial light may be a possible reason why bipolar disorder cases have been increasing in modern times. In the past, the sleep and wake cycles of most people were controlled by the sun. Being exposed to artificial light would make people more susceptible to bipolar disorder. However, the exact cause is still not fully understood. [4]
